Heat Bed Not Heating Properly

Okay, so I might have messed up my heat bed. I printed a large object a couple of weeks ago after scuffing the heat bed to make it stick better, and boy did it stick. As a matter of fact it stuck to the bed so well that when I was trying to get it off the bed, part of the PEI sheet pulled up. So now I have a bed with a large chunk of Pei Sheet missing. This chunk is off to the side and won't have a major effect on my printing from the middle to the other side. The problem is that since that incident I can't get the heat bed to heat. It will slowly heat up but it never reaches the proper temperature. I was messing with it this morning and discovered it is still heating around the sides but not in the middle of the plate. So do you think I might have flexed the heat bed while removing the print? (My screws that are supposed to secure the middle didn't fit when I put the bed on so I left them out. I realize that was stupid now) So any help would help me, I would really like to know if I can read the resistance and find out for sure. Thanks.

The heated bed, when properly working, should measure only about 1 Ohm. Unfortunately, there is some variation in this value, so it may not be possible to check with a DMM.

I think it does rather sound as though you need a replacement. Contact support - use the "live chat" on the shop pages and give them a link to this thread.
